SITUATION OVERVIEW
------------------
...OVERVIEW...At 400 PM CDT, Tropical Storm Nate is moving toward
the north- northwest near 20 mph and is expected to continue on this
general heading through Saturday night into early Sunday. The main
impacts across southeast Louisiana and south Mississippi will be
damaging winds and storm surge flooding along the immediate coast and
tidal locations.
POTENTIAL IMPACTS
-----------------
* SURGE:
Protect against life-threatening surge having possible extensive
impacts across coastal and tidal locations in both Southeast
Louisiana and Mississippi including the shores of Lake Pontchartrain
outside of the hurricane risk reduction system.
Potential impacts in this area include:
- Large areas of deep inundation with storm surge flooding
accentuated by battering waves. Structural damage to buildings,
with several washing away. Damage compounded by floating
debris. Locations may be uninhabitable for an extended period.
- Large sections of near-shore escape routes and secondary roads
washed out or severely flooded. Flood control systems and
barriers may become stressed.
- Severe beach erosion with significant dune loss.
- Major damage to marinas, docks, boardwalks, and piers. Many
small craft broken away from moorings, especially in
unprotected anchorages with some lifted onshore and stranded.
Elsewhere across Southeast Louisiana and South Mississippi, little to
no impact is anticipated.
* WIND:
Protect against life-threatening wind having possible extensive
impacts across extreme Southeast Louisiana and coastal Mississippi.
Potential impacts in this area include:
- Considerable roof damage to sturdy buildings, with some having
window, door, and garage door failures leading to structural
damage. Mobile homes severely damaged, with some destroyed.
Damage accentuated by airborne projectiles. Locations may be
uninhabitable for weeks.
- Many large trees snapped or uprooted along with fences and
roadway signs blown over.
- Some roads impassable from large debris, and more within urban
or heavily wooded places. Several bridges, causeways, and
access routes impassable.
- Large areas with power and communications outages.
Also, protect against dangerous wind having possible limited to
significant impacts across portions of Southeast Louisiana mainly
along and east of the Interstate 55 corridor including metro New
Orleans...River Parishes...and Bayou Region near Houma.
* FLOODING RAIN:
Protect against locally hazardous rainfall flooding having possible
limited impacts across coastal Mississippi and portions of Southeast
Louisiana mainly east of the Interstate 55 corridor.
Potential impacts include:
- Localized rainfall flooding may prompt a few evacuations.
- Rivers and tributaries may quickly rise with swifter currents.
Small streams, creeks, canals, bayous, and ditches may become
swollen and overflow in spots.
- Flood waters can enter a few structures, especially in usually
vulnerable spots. A few places where rapid ponding of water
occurs at underpasses, low-lying spots, and poor drainage
areas. Several storm drains and retention ponds become
near-full and begin to overflow. Some brief road and bridge
closures.
Elsewhere across Southeast Louisiana and South Mississippi, little to
no impact is anticipated.
* TORNADOES:
Protect against a tornado event having possible limited impacts
across portions of extreme Southeast Louisiana and coastal
Mississippi.
Potential impacts include:
- The occurrence of isolated tornadoes can hinder the execution
of emergency plans during tropical events.
- A few places may experience tornado damage, along with power
and communications disruptions.
- Locations could realize roofs peeled off buildings, chimneys
toppled, mobile homes pushed off foundations or overturned,
large tree tops and branches snapped off, shallow-rooted trees
knocked over, moving vehicles blown off roads, and small boats
pulled from moorings.
Elsewhere across Southeast Louisiana and South Mississippi, little to
no impact is anticipated.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* EVACUATIONS:
For those under evacuation orders, leave as soon as practical with
a destination in mind. Gas up your vehicle well ahead of time. Be
sure that you take all essential materials from your emergency
supplies kit. Let others know where you are going and when you
intend to arrive.
For those not under evacuation orders, understand that there are
inherent risks to evacuation (such as traffic congestion, accidents,
and driving in bad weather), so evacuate only if necessary. Help
keep roadways open for those that are under evacuation orders.
If evacuating away from the area or relocating to a nearby shelter,
leave early before weather conditions become hazardous.
* OTHER PREPAREDNESS INFORMATION:
Now is the time to bring to completion all preparations to protect
life and property in accordance with your emergency plan.
Outside preparations should be wrapped up as soon as possible before
weather conditions completely deteriorate. Any remaining evacuations
and relocations should be expedited before the onset of tropical
storm force wind.
Keep cell phones well charged and handy. Also, cell phone chargers
for automobiles can be helpful after the storm. Locate your chargers
and keep them with your cell phone. If you are a visitor and still
in the area, listen for the name of the city or town in which you
are staying within local news updates. Be sure you know the name of
the county or parish in which it resides. Pay attention for
instructions from local authorities.
Closely monitor NOAA Weather radio or other local news outlets for
official storm information. Be ready to adapt to possible changes to
the forecast.
